Welcome to SolarWinds blog series “The Best Practices for Optimizing Alerts”. This is the first of 3 part series where you can learn about the best practices for optimizing your network alerts in your environment. In this blog we will discuss threshold based alerting and its importance in maintaining ideal network performance.
What are Network Alerts?
A network alert is a notification which informs the network administrator of an abnormal event that has occurred in the network. Alerting allows network administrators to be aware of the events that directly affect the health of their network so that the administrators can resolve the issue proactively before the problem directly affects the user. Automated alerts can be set to be delivered through a variety of methods such as email or text.
Monitoring and managing alerts is an important function for any network administrator who wants to ensure continuous network availability. With increasing network complexity, alerting can become very “noisy” as network managers are bombarded with series of notifications about all the activities and issues in network. Intelligent alerting will help avoid unnecessary notifications so you can focus on those that are most important.
How Threshold based Alerting helps Network Administrators
Threshold based alerting can help reduce the “noise” by limiting notifications to only those that cross a pre-defined threshold. For example, if a network administrator sets the bandwidth usage of a critical interface to a limit of 80%, he will be alerted when the usage exceeds that limit. Similarly, if the CPU utilization exceeds 80% limit, you will be alerted about the impending situation so you can check what device or application is using the memory.
Maintaining High Performance through Intelligent Alerts
Threshold based alerting helps you to troubleshoot a network situation and keep your problems at bay. Almost all network monitoring tools include alerting to notify you when an event occurs..
What you really need, however, is Intelligent Network Alerting. With intelligent alerting you can define device dependencies to ensure you don’t receive unnecessary alerts, configure alerts for correlated events and escalate alerts to a variety of delivery methods.
By monitoring your network and optimizing your intelligent alerts you can find and correct issues before your network performance gets affected by degradation or availability issues.
